Test for measuring PH, KH and GH Lawana pond test

  Unfavorable water values mean stress, increased susceptibility to diseases and slow growth of lake inhabitants. That's why it's important to measure water quality regularly. The product is a reusable test that is suitable for ponds. It serves to measure the following values - pH, carbonate and total water hardness. How to use : Total hardness test GH: Color change test => Add reagent drop by drop until the color changes from red to green. Number of drops = total hardness
KH Carbonate Hardness Test: Color Change Test => Add reagent drop by drop until the color changes from blue to yellow. Number of drops = carbonate hardness
